Tales of Monkey Island DVD with added Features?

Does anybody know if the Bonus DVD that we will all be recieving at the end of the 5 episodes, will contain extra bonus material, like a making of, a short movie etc...or is it just going to be the 5 games only?

i'm pretty sure that there will be some bonus content on the disc, just like on the sam & max discs and on the sbcg4ac disc.... but imho it's to soon for telltale to say exactly what will be on disc and what will not...
